fix(qizheng): copy vendored stem-branch files from local upstream checkout

Read G:/Ferti/yinduzhanxing-codex-add-birth-time-rectification-skill (a911c890) and copy the listed vendor files by content. Rebuild the adapter from the 168-line CLI wrapper, then apply school parameters, boundary rewrite, and sanitized errors.
